However, nothing will close the editor after the first cancel except clicking on another grid row.Is there a way to manually close the editor when in Batch Edit Mode?Hi, When using batch editing the user entered data should be first validated on the client.For that purpose you can subscibe to the On Batch Edit Closing or On Batch Edit Cell Value Changing event, obtain the entered value and check whether it meets your criteria.In cases like the described where multiple clicks will be performed our of the grid and it will try to close the cell/row you will have to ensure that the In Notes flag value is correct and that it will only cancel the event when you need it to. Once the args.set_cancel is set to true, the row will not close manually through code.Is there no other way to accept the changes entered and close the row?If not you can cancel the event(thus preventing the cell from closing) and display an alert message notifying the user that the data is not valid.One other thing, you can also validate the data on the server by subscribing to the On Batch Edit Command event and extracting it from the event arguments as shown here.

Do you want to know when a feature you care about is added or when a bug fixed?

Form View 介绍 Form View就是完全由用户定义,所以Template也多,有Item Template, Edit Item Template, Insert Item Template, Footer Template, Header Template, Empty Data Template, Pager Template.

NET, los desarrolladores nos confiamos y dejamos de lado la validación de los datos en el servidor y esto no es una buena practica, puesto que en un formulario donde todos los datos son obligatorios, puede ser que por algún motivo vengan vacíos y nos den de vez en cuando algún disgusto, aunque es verdad que una doble validación cliente-servidor implica mas tiempo de proceso y por consiguiente menos rendimiento, pero aumenta la seguridad tan importante hoy en día.

Hello, Can you please share with us the page code and elaborate on the scenario so we could try and find out what prevents the cell from closing?

Generally you can call an our internal method (provided below) that closes the edited cell/cells but the use of internal methods is not the suggested way.I have a grid which has the Add/Save/Cancel command as Command Items. During insert/update, I want to validate the values after the user enters values and throw an error message on clicking Save.
